Specification of Letters Patent. Appneation sied Mays, 191s.

To all whom t may concern Be it known that I, DENIS W. DALEY, a citizenof the United States, residing in Parkersburg, inthe county of Nood andState .of lWestV Virginia, have invented an Improvement in RemovableSupports for Sides of Concrete-Molds, of which the following is aspecification.`

In molding the walls or concrete or cement structures it is necessary tosupport horizontally and at diiierent heights the side boards of themolds between which concrete or cement is to be poured to form a sectionof the wall.

I have devised an' improved apparatusior this purpose, and the same ishereinafter described with reference to the accompanying drawing, `inwhich- Figure l is a vertical section ot a concrete wall and oi myapparatus in place thereon, and supporting side mold-boards in theposition required for receiving plastic material between them. Fig. 2 isa sectional perspective view of a concrete wall with my apparatusapplied in position' to support side and, Fig. 3 is a sectionalperspective view ot the same parts las shown in Fig. 2, but withmold-boards added and arranged as shown in Fig. 1. v

The apparatus is formed of duplicate sets ot bars A and B, and tworight-angular D. The duplicate sets are in practice, arranged onopposite sides of a concrete or cement wall, and are secured to- 'tionon the sides of the wall section. When thus applied, side mold-boards Grrest upon the brackets and their outer sides lie against the portions otthe bars A that project above (not shown) which may be used to hold thebars A and B more firmly in due vertical position, andalso preventingthe same turning on their axles.

lt is apparent that when the mold-boards G are supported in the mannerindicated in Figs. l and 3, plastic concrete or cement may be pouredinto the space between them and will thus form an additional orsuperadded section of the wall. tion has set, the pins F are removedfrom the end of the twisted wire E, which permits detachment and removalof the duplicate supports from the wall.

rllie bars A and B may be constructed of metal or wood, and thebracketsare preter- `ably constructed of metal.

What I claim is:

l. An apparatus Jfor the purpose specitied, comprising duplicate sets ofbars, outer ones of each side projecting above the inner ones, andsecured thereto and right angular brackets secured to the bars at theupper ends of the shorter ones, the horizontal portions of said bracketsprojectinginwardly so as to overlap a concrete wall section, and meansJfor securing the duplicate sets together when appliedy onopposite-sides of a wall, as shown and described.

2. An improved apparatus Ior the' purpose specified, comprising a set ofbars arranged side by side, and secured together, one of said bars beinglonger than the other,

Lwall by suitable means, which in thisy instance is a twisted wire Ewhose ends eX- tend across the wall section and pass through the barsandare secured temporarily in position by meansof pins F. The two bars oi"each duplicate set are laid together lengthwise `and secured in thatposition by suitrllhe bars A are about onethird (-2,) longer than thebars B and pro` ject above the latter whose upper ends support sidemold-boards Gr. The right-angular brackets D are so applied that thevertical flange is clamped between the bars A and B, while thehorizontal ilanges overlie and rest upon the top surface of the concretewall section already formed. These brackets D serve as the means forsupporting the dupliother bracket at the bottom ofthe longer bar, asdescribed. A
